After the roundabout is removed, a temporary one will remain in place while the lights are installed.

New trees will be planted in areas near the junction to replace those lost during the work.

Councillor Chris Turrell, Bracknell Forest Council’s executive member for planning and transport, said: “The Coral Reef junction will only be able to cope with the increased traffic flows in future if we make these changes. The scheme will reduce congestion and improve travel through the borough in the years to come.

“We’re aware some residents will be concerned at the idea of removing trees for the scheme and the possible impact on local wildlife.

“That’s why we are removing the trees now before the birds start nesting and why we will be planting some replacement trees in the adjoining neighbourhoods.

“Our engineers, parks and countryside and environmental teams are working closely to identify the best spots for new trees to make sure they thrive.”

The work will take around 18 months to complete and the lights are expected to fully open by autumn 2016.

Bracknell Forest Council bosses say the work phases have been designed to limit the impact of the work on traffic flows.
